DB Architect / Consultant at Virtusa Global
Room for improvement in data handling leads to enhanced cost-effective data management performance
It would be beneficial if MongoDB Atlas could better support OLTP aspects and data frames, as well as enhance its capabilities for data pipelines and visualization dashboards. Furthermore, supporting the medallion architecture could be a valuable addition, and incorporating improved spatial and vector handling for geographical data could make it more competitive. Enhancing vector processing for AI capabilities would also be critical.

Have achieved excellent performance and seamless integration with effective cost control in cloud solutions
When customers are migrating from Oracle Exadata Express Cloud Service and need to remove some of their test and development environment, what happens in normal virtualization is that they can just switch it off, but in ExaCS, they need to terminate the entire thing. Most of the customers are not aware of this, so they keep spending money even if they want to shut down their UAT environment or development environment, so Oracle needs to make it simpler in terms of reducing the bill on ExaCS when customers want to shut down certain environments. Today, you have to terminate the entire VM, and only then your billing will stop. The only functionality I would expect from Oracle Exadata Express Cloud Service is that if Oracle is able to support Oracle MySQL Enterprise also on Exadata, that will solve a lot of problems.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I am impressed with the tool's integrations."
"It can store data as a flat file, similar to a file system."
"The solution is easily scalable and manageable. Tools can be easily added to the solution."
"The product is user-friendly."
"The speed of it is the most valuable feature."
"The cloud-based nature of this solution makes it flexible and scalable."
"MongoDB Atlas is a database that is quite fast, stable, and reliable."
"It enables us to get work done quickly and get to our data."
"It is a scalable product."
"I highly recommend Oracle Exadata Express Cloud Service as a very good solution if you can afford it."
"The performance of the tool is valuable."
"I would rate Oracle Exadata Express Cloud Service ten out of ten for its overall solution."
"Having the prediction happen in the modular format allows you to start with a lower version of Exadata and then you can keep on upgrading it as per your requirement."
"One of the most valuable parts of the solution is the high availability within the system and the performance enhancement without making any changes or fine-tuning the databases."
"The solution is very stable and offers great performance."
"In the cloud, Exadata is more scalable. The on-prem version was limited. It wasn't that scalable because it only came in a quarter rack, half rack, and full rack. In the cloud, it scales to what you need."
 

Cons

"The web console isn't very intuitive, especially for large data."
"Querying a dataset is not very intuitive, so I think that it can be improved."
"Searching and browsing through the collection must be made easier."
"MongoDB Atlas should add more APIs in their Terraform module because sometimes I find it difficult to find the resources in their Terraform model."
"The price of the solution should be reduced."
"The biggest challenge we all have is an application layer level. One node is sitting in the APAC region, another node is sitting in the US and UK region. The seamless replication has to be lightning fast, but we haven't tested the scalability yet."
"The product's data aggregation feature needs to work faster."
"We had some bad trainers when we first came onboard and would rate them fairly low. They did not seem staffed properly to fulfill the training services that they offered."
"Scaling Oracle Exadata Express Cloud Service can be done, but the process is a little tedious, which could be an area for improvement in the solution."
"The support must be faster."
"The only downside is the difficulty in monitoring, and that's why I would like to implement MySQL database."
"Oracle's support could be better."
"We use artificial intelligence for deep learning, and it would be a huge benefit to implement this in Oracle Exadata."
"The product's installation process needs improvement. It could be more accessible."
"The solution's pricing could be improved."
"The customer's default choice is the on-premise version of this solution. Only when Oracle or the partners like us, can explain to customers the cloud value proposition, and if the compliance authorities allow, they can look into this cloud solution. It will take some time for Oracle to change its perception of customers' de-facto standards. Exadata used to be treated as a black box, which is not the case now. The customer is aware of what is happening inside, how the configurations have been made, and what patching has been applied. Oracle needs to market the cloud version better."
 

Pricing and Cost Advice

"The solution is expensive overall. It does not require a license but if you want the support then you will need to purchase the license. They use a pay-as-you-go model and you are able to receive some discounts by making longer usage commitments."
"I have seen the cost, and it was pretty cheap."
"Comparing the price between the MongoDB and Microsoft SQL Server, we are using the enterprise edition of Microsoft SQL Server, which is more expensive than MongoDB."
"The solution is fairly priced. I rate the pricing a seven out of ten."
"It is an open-source platform."
"MongoDB Atlas is more cost-effective than Amazon DocumentDB. It also has a pay-as-you-go pricing model. Apart from the standard licensing cost, you must also pay to get MongoDB Atlas technical support, which is expensive."
"It is too expensive. They need to work on this."
"Pricing could always be better."
"The price of this solution is very comparative to others on the market. There is no direct comparison between this solution and with something else because I do not see any other similar product."
"I think Oracle pricing is usually above average market price."
"The tool is not cheap, but it is not really expensive."
